Apple, today, has filed a lawsuit against Motorola over their use of Qualcomm technology, as reported by Reuters. Apple explains that Motorola has breached a contract pertaining to their use of a patent license and “asks this Court to enjoin Motorola from prosecuting and 4 enforcing its claims against Apple in Germany.”

Specifically, Apple is suing Motorola over their claims that Apple is illegally using Qualcomm’s baseband chip. In its lawsuit, Apple asks the court to ban Motorola from being able to sue Apple over Apple’s use of Qualcomm’s technology:

Permanent injunctive relief restraining Motorola and its subsidiaries, affiliates, officers, directors, agents, employees, servants, licensors, successors, assigns, and all those acting in concert with them, from prosecuting patent infringement proceedings against Apple based on Apple’s use of the Qualcomm MDM6610 chip and other Qualcomm components licensed under Motorola patents in any forum other than this Court

The root of the lawsuit is essentially Apple’s strike-back at Motorola for attempting to stop sales of Apple’s 3G products in Germany. The lawsuit’s referencing of Qualcomm’s chips is a nod to the iPhone 4S, which uses a Qualcomm baseband chip, not being removed for that short amount of time when Apple won a temporary injunction of Apple’s 3G products in Germany.
